Spray shield with trough

ABSTRACT

The present invention is directed to a shield fabricated from a sheet of material having a trough disposed on the lower edge and peripheral flanges disposed about the remaining edges for confining excess spray/mist when positioned rearwardly of an object being painted, cleaned or otherwise treated and directing it to the trough where it is collected and discharged. More specifically, the shield is fabricated from any of a variety of materials including cardboard, plastic, tin, stainless steel, etc., may optionally be provided with a coating to enhance the flow of the excess spray/mist downwardly into the trough, and is provided with means for suspending, staking or wedging the same onto support means during use.

BACKGROUND OF THE INVENTION

The present invention concerns itself with treating surfaces with sprayable material and confining the excess spray which can cause damage to other structure, plants. etc. if discharged into the atmosphere. Shields for protecting adjacent or nearby surfaces are well documented in the prior art and, in the course of a search in the United States Patent Office, U.S. Pat. No. 4,005,678 was deemed to be the nearest to that of the present invention. The shield of this patent is comprised of a planar spray-engaging surface having a spray-collecting trough at the lower edge thereof from where it is disposed. The shield of the present invention is an improvement over said shield in that it provides a spray-containing flange disposed therearound along with means to support the same in vertical as well as other positions during use.

These features were not contemplated by the patentee of U.S. Pat. No. 4,005,678 in that the shield thereof is obviously designed for light-duty spraying, such as house plant treatments, and has no means for stabilizing the same in a vertical or other position for heavy-duty spraying as is the case in the present invention.

SUMMARY OF THE INVENTION

The present invention is directed to a shield which is designed to confine and collect excess spray in a simple and efficient manner when treating an object. Simply, the shield is comprised of a planar sheet of any suitable material having a peripheral guard means and a collection trough disposed thereon, and means associated therewith for supporting the same in various use positions. The invention also contemplates various methods of and materials for making the same.

DESCRIPTION OF THE INVENTION

With reference to FIGS. 1, 2 and 3 of the drawings, the shield of the present invention is designated generally as 10, and is seen to include a generally planar sheet of material 11 having an upper angled outwardly extending section 12 coextensive therewith, a trough 13 extending along the lower edge thereof, peripheral flange means 14 extending along the edges of the sheet, spaced support engaging arms 15,15 extending beneath and outwardly in the same direction as said angled section 12, and handle means 16,15 on the outer surface of said section 12 to facilitate handling of the shield 10. As seen in these Figures and to use the shield 10, the user grasps the handles 16,16 lifts the same and disposes the support arms 15,15 with its downturned ends E1,E1 (FIG. 3), over a surface S to be treated, with the ends engaging the same for supporting the shield therefrom. In this instance and merely by way of example, the support surface S is a top rail of a railing, fence, or the like which is to be treated. The user then directs the spray of material which can be paint, cleaning or treatment solution, etc. against the same whereby the excess spray is directed against the surface 11 with the peripheral guard 14 confining the excess spray therewithin and directs the same downwardly into the trough 13 where it is collected for disposal or reuse. After this section is treated, the shield is moved along the support surfaces until the entire railing, fence, etc. is completely treated.

By confining the spray the same is not discharged into the atmosphere where it can cause harm and damage to adjacent structures or the like. Thereafter the collected spray is dispensed from the trough 13 via opening 17 having a closure means 18 (FIG. 3A), which can optionally be a plug, sliding valve 18, etc. or, alternatively, a hose 19 may be utilized for continually draining the collected fluid therefrom for disposal or reuse.

The shield 10 of FIGS. 1, 2 and 3 is designed for heavy-duty use which encompasses continual commercial reuse and is fabricated from steel, tin, aluminum, or any other heavy-duty material. A further modification is seen in FIG. 3B wherein the shield is made from sections which can be readily extended to compensate for varying length of surfaces to be treated. As seen, the shield is fabricated from several like sheets 11,11 with the peripheral flanges 14,14 of each sheet being in telescoping frictional engagement whereby one sheet can be extended relative to the other.

Alternatively, the shield can be made of readily disposable material such as cardboard, plastic, etc. and, as seen in FIG. 4, the shield 10 is formed from a cardboard blank having a major surface 11 with scored edges 14a disposed inwardly and around the peripheral edges whereby the same can be folded therealong to form the top section B, flanges D, and trough C. The formation of the trough is formed by bending the two sections and can be held in place by inserting the tabs 14b into the accommodating slots 11a or by stapling the same to the planar surface 11 as seen in FIG. 4A. In this embodiment the shield can be held in place during use by string, wire, nails, or by securing pivotal ground-engaging stakes 20,20 to the rear of the main surface 11. In this embodiment, and if desired the shield can be coated with a material to enhance the flow of the spray downwardly into the trough.

As seen in FIG. 5, the shield can also be formed from a sheet of plastic with the peripheral guard means and trough already formed therein, or from a flexible sheet of plastic which will automatically reroll after the tension is removed therefrom.

As is apparent the shield of the FIG. 4 and FIG. 5 embodiments is designed to be readily stored and/or disposed after usage and is, therefore, made from relatively inexpensive and readily available material.

It will be appreciated that the preceding descriptions and examples of the invention are examples only and that further improvements may be apparent from this disclosure and may be resorted to without departing from the spirit of this invention, as those skilled in the art will readily understand.
